Hazelia is a genus of spicular Cambrian demosponge known from the Burgess Shale, the Marjum formation of Utah,[1] and possibly Chengjiang.[2] It was described by Charles Walcott in 1920.[3]

Its tracts are mainly radial and anastomose to form an irregular skeleton.[1] Its oxeas form a fine net in the skin of the sponge.[1]
